CARL A. GASPERSSON, OF WESTANFORS, SWEDEN.

CASTING APPARATUS.

SPECIFICATION forming part of Letters Patent N o. 229,953, dated July 13, 1880. Application filed April 12, 1880. (No model.) Patented in Sweden May 28, 1879; in England, February "l, 1880. i

To all whom it may concern:

Be it known that I, CARL AUGUST GASPERS- SON, a subject ofthe king of Sweden, residing at VVestanfors, in the county of Westmanland, in the Kingdom of Sweden, have invented certain new and usefulImprovements in Casting Apparatus; and I do hereby declare the following to he a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to t-he accompanying drawings, on which- Figure 1 represents a side elevation, Fig. 2 a central longitudinal section, Fig. 3 a plan view, and Fig. 4 an end view, of the improved ladle. Fig. 5 represents a sectional View, and Fig 6 a side elevation, ofthe ladle as secured to a Bessemer-furnace or converter.

This invention ot' an improved casting apparatus, which I. call converter-ladle," relates to arrangements enahlin g the casting of Bessemer iron or steel to be made more directly from the converter into the molds than what has hitherto been the case.

When the blow of a Bessemer charge is fmished and the converter has been partly turned the ladle A is closely fixed to the convertermouth F', as shown in Fig. 6. The converter F is turned still farther, as shown in Fig. 5, or so much that it' it was not for the attached ladle A the converter would be evacuated. The duid iron or steel then stands partly in the converter and partly in the ladle, and when the molds, which are standing either on a turntable or on wagons, have been carried beneath the ladle the iiuid iron or steel can be cast through its bottom. In this way much heat will be saved, which is lost bythe usual mode of casting by means ot' a ladle which receives the whole mass of fluid metal and is then moved over a row of standing molds. In consequence of the saved heat no metal is left in the converter-ladle A on account of cooling, and for the same reason the soundness of the ingots is very much improved.

Another advantage of the converter-ladle is that the same, even when the casting of the metal into the molds is performed with the usual ladle, makes it possible in a convenient way to get the metal in the last-mentioned 1adle separated from the slag in the converter, which in some cases-as, for instance, when phosphureted pig-iron is employedmay be of great importance.

The converter-ladle A is furnished not only with the common apparatus, as shown, for

' the converter-mouth.

The ladle is made of sheet-iron or other suitable material, and lined with ganister or any other refractory substance. The side openin g, A', must it exactly to the mouth F' of the converter F, to which it can be closely xed by means ofthe eyes B B B and wedges C, Fig. 6, or in any other suitable manner.

The ladle A being fixed to the converter F, the casting takes place through the hole E in the bottom, as shown in Fig. 5. The ladle A is carried to and from the converter F by the aid of a swing, D, and a crane, or in any other way, and even when fixed to the converter the ladle is partly or altogether supported in the same way.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- A casting-ladle, A, which, besides the usual opening E in bottomfor tapping in the usual way, has also an opening, A', at its side adapted to t to the mouth of the converter for which it is to be used, and havingafastening device for securing them together, as and for the purpose set forth.

In testimony that I claim the foregoing as my own invention I have aflixed my signature in presence of two witnesses.

CARL AUGUST OASPERSSON.
